Loose-it-all machine
Švik, Ondřej ; Hůlka, Tomáš (referee) ; Cejpek, Zdeněk (advisor)
This bachelor thesis deals with the design and construction of a prototype of a “lose-it all” machine for educational purposes. The lose-it-all machine serves to implement a simple gambling game. The machine uses proprietary jettons as currency. The practical part of this bachelor’s thesis is dedicated to the description of the functionality, design, basic features, build construction, and the software solutions of the machine. It describes the physical implementation and creation of the various necessary parts of the lose-it-all machine. The theoretical part of this thesis includes research about gambling as well as an introduction to hazard addiction and its prevention.

Remote control of low voltage curcuit-breaker
Brtnický, Jiří ; ABB, Stanislav Korčián, (referee) ; Bajer, Arnošt (advisor)
The work deals with design and contruction of the extension module remote control, through which the starter motor is remotely controlled. On the basis of specified input parameters such as size, engine type, engine power, voltage, etc., is given control module design, which includes a control unit (microprocessor) for remote control of motor drive and assessment of motor starters. The work also includes analysis of the problems of mechanical transmission, depending on the management and selection of an engine. This work is finished with the physical realization of a prototype control program by drawing a flowchart and manufacture of printed circuit boards with subsequent recovery and testing.

Controlling of stepper motor
Semrád, Michal ; Žalud, Luděk (referee) ; Kopečný, Lukáš (advisor)
Bachelor’s thesis discusses about the fundamental issues of stepper motors. The following text provides an overview of different types of stepper motors and explains how they can be controlled. Followed is chosen the stepper motor, which is controlled by using driver A4988 and evaluation kit Primer STM32C. Graphic user interface is created on the LCD display of the evaluation kit.

Electronics and CNC milling machine control
Tmej, Tomáš ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
The diploma thesis focuses on the electronics design of a hobby CNC milling machine. There are analysed and described the individual electronic parts and components related to this problematic. Three electronics suggestions are made, these suggestions are compared. Then, one of these variants is selected and implemented. Next, is created a relevant PLC program to control the CNC milling machine with visualization for easy control.

Design of the rotary rack for the IRB 4400 robot tools
Palčík, Jakub ; Tůma, Zdeněk (referee) ; Štěpánek, Vojtěch (advisor)
This work deals with design of rotary tool changer for automatic tool change in robot cell. In addition some research have been done on possible components that will be used in design. Than is made 3D model of design. Main purpose of design is to maximize simpilicity. After this designing phase, this design is checked by technical calculations obout required torgue from motor and basic calculation about strength and stiffness. Finally is created assembly drawing and bearing housing drawing .

Electronics for Sewing Machine
Karásek, Josef ; Fedra, Zbyněk (referee) ; Vychodil, Josef (advisor)
The main components of the system for embroidery sewing machine is (Veritas 8014/35-2) and pointing devices. The machine automatically entered embroidered patterns, it is necessary to construct a pointing device and its control. To drive the pointing device used two stepper motors, the control circuit to cater to the ATmega128. Communication between PC and ATmega128 provides converter FT232.

Rotary manipulator for manual welding of hoist drums for EXYZ storage machine
Pečenka, Tomáš ; Komenda, Adam (referee) ; Škopán, Miroslav (advisor)
The main aim of this diploma thesis is to design rotary manipulator for manual welding of hoist drums for EXYZ storage machine. The rotary manipulator is designed for improving of the quality of welds, which have been made in the static bearing welding process of hoist drum. The first part is concerned on the critical research of welding manipulators, which could be founded on the market. In the next part, there are sketched possible construction designs of welding manipulator based on the market offer. The main part of the diploma thesis is own construction design, which is made on the base of suggested concept of construction design.

Possibilities of controlling the output characteristics of the peristaltic pump
Odehnal, Martin ; Formánek, Martin (referee) ; Jagoš, Jiří (advisor)
This bachelor's thesis deals with the possibilities of controlling the output characteristics of a peristaltic pump. First, the peristaltic pumps themselves, their design and principles of operation are analyzed. Furthermore, their applications and a description of their use in biomedical applications are described. The main part of this review describes the output characteristics of a peristaltic pump with a follow-up chapter devoted to the possibilities of their control. Here, the options are divided according to their nature into three groups: software, hardware and their combinations. The possibility of variable speed control during the cycle belongs to the category of software control and its implementation is performed in the practical part of this work. This option was chosen due to its universal use, both in the elimination and modulation of pulsation. As part of the work, different schemes were designed that allow variable control of the rotor speed of the stepper motor during one revolution in four modes according to the choice of speed profile.
